50 T/H BB Fertilizer Rotary Drum Blending Line for Zimbabwe Customer (2025)

Project Overview

In 2025, our company successfully completed the manufacturing, delivery, installation, and commissioning of a 50 tons per hour BB fertilizer rotary drum blending line for a leading agricultural input supplier in Zimbabwe.

The project was designed to meet the customer’s growing demand for high-capacity bulk blending fertilizer production while ensuring accurate nutrient ratios, uniform mixing performance, and efficient continuous operation. With this new production line, the customer significantly enhanced production efficiency and strengthened its supply capability for the Southern African fertilizer market.

Customer Background

The customer is an established fertilizer distributor and producer serving Zimbabwe’s major agricultural sectors, including:

• Maize farming
• Tobacco cultivation
• Wheat production
• Cotton plantations
• Commercial vegetable farming

As fertilizer demand continued to increase, the customer faced several production challenges with its previous equipment:

• Insufficient output capacity during peak season
• Inconsistent blending uniformity
• High labor intensity
• Dust generation during production
• Limited automation level
• Difficulty producing multiple customized formulas efficiently

To solve these issues, the customer invested in a new 50 T/H BB fertilizer rotary drum blending line.

Project Objectives

The customer requested a complete solution with the following objectives:

1. Production capacity of 50 tons/hour
2. High blending uniformity for NPK bulk fertilizers
3. Automatic batching and feeding system
4. Continuous and stable operation
5. Low maintenance cost
6. Easy formula switching
7. Reliable performance under local operating conditions

Our Technical Solution

Based on the customer’s raw materials, plant layout, and target formulas, our engineering team designed a customized BB fertilizer rotary drum blending system.

Main Equipment Supplied

• Raw material storage bins
• Automatic batching system
• Belt feeding conveyors
• Rotary drum blending machine
• Bucket elevator
• Buffer hopper
• Automatic weighing and bagging machine
• Dust collection system
• PLC control cabinet
• Steel platform and support structure

Production Process

The production flow of the line is:

Raw Materials Storage → Automatic Batching → Conveying → Rotary Drum Mixing → Buffer Storage → Automatic Packaging

The system is suitable for blending common fertilizer materials such as:

• Urea
• DAP
• MAP
• Potassium chloride (MOP)
• Ammonium sulfate
• Granular additives
• Micronutrients

Core Advantages of the Rotary Drum Blending Line

1. High Capacity Production

With an output of 50 T/H, the line fully satisfies large seasonal fertilizer demand and improves delivery speed to distributors and farms.

2. Excellent Mixing Uniformity

The rotary drum blender ensures full material movement and even nutrient distribution, producing consistent high-quality BB fertilizer.

3. Gentle Material Handling

The optimized internal structure minimizes particle breakage and preserves granule integrity, which is critical for bulk blended fertilizer.

4. Flexible Formula Production

The customer can quickly switch between different formulas such as:

• 15-15-15
• 10-20-10
• 20-10-10
• Tobacco special blends
• Customer-specific NPK grades

5. Intelligent Automation

The PLC control system provides:

• Automatic ingredient weighing
• Formula memory storage
• Centralized machine control
• Real-time monitoring
• Alarm protection system

6. Low Dust and Clean Operation

The enclosed conveying and dust collection design improves the working environment and reduces material loss.

Installation and Commissioning

Our technical team provided complete project support, including:

• Equipment layout design
• Foundation drawings
• Installation guidance
• Electrical connection support
• Trial production testing
• Operator training

After commissioning in 2025, the line reached stable operation quickly and met the designed production target.
